SPI-Chem Stains for Electron Microscopy

SPI Supplies offers a complete collection of known electron dense stains, both positive and negative, for use with transmission electron microscopy procedures. Some of these stains are becoming more and more difficult to obtain because of increasingly tighter environmental regulations, and when they are available, the cost to produce them is skyrocketing. So we apologize in advance if the prices paid appear to be escalating faster than the general inflation rate.
